To make this enforceable...you’d need ISP police running around and double-checking all the ISP providers. I’m guessing it’d take a year or two for them to figure that out...and then some new division of Federal Marshals or FBI would be playing ISP police.
The technology already exists to beat this, so it is comical that it’s about ten years behind the times.
Finding them would be a problem. Lots of the mom-and-pop country WISPs are a cell phone and a PO box.
Order service, and someone comes out and puts up a radio on your roof and goes away. Bill comes once a month... etc...
Sure, the hardware could be found, and everything traced... But lots of times, there are no offices. Just field equipment and a POP. The Feds come with locks to put on doors. What do they do where there is no door, or even there, there?
If it was me, I'd run normally until official problems, and then shut down and explain why.
I didn't get this old without learning when to walk away from a problem.
But make money right up until then.
